The measure of dispersion that measures how much the data differ from the mean is called the standard deviation.
<h3>What is standard deviation?</h3>
Standard deviation is a statistical measure of dispersion as opposed to the measure of central tendency like mean, median and mode.
The standard deviation is a measure of how spread out data values are around the mean.
It is defined as the square root of the variance and represented with the Greek letter σ.
